The old-fashioned way of making it is with white flour. Try this way. Whip the eggs well, and make a batter of the eggs, milk, meal and oats, adding pepper and salt. Pour the mixture into a shallow Yorkshire pudding tin, which has been previously well buttered. Scatter a few bits of butter on the top, and bake the pudding for 1 hour. Serve with baked potatoes, green vegetables, and sauce.
